Abstract
An integration circuit integrates an angular velocity signal outputted from a vibration detection element and generates a shift amount signal indicating the shift amount of an imaging device. The integration circuit is formed by a digital filter, which includes a register for holding an accumulation value serving as a shift amount signal. A control unit acquires an accumulation values held in the register at a predetermined interval and obtains a change amount between the accumulation value previously obtained and the accumulation value currently obtained. When the change value exceeds a predetermined threshold value, the control unit subtracts a correction value from the currently obtained accumulation value so that the value approaches zero and resets the obtained value in the register.
